16-Bit GMSL Serializer with High-Immunity/Bandwidth Mode and Coax/STP Cable Drive

Compact 1.6Gbps Serializer with Crosspoint and CRC Protection of Video and Control Data for ADAS Applications

Product Details

The MAX96705A is a compact serializer with features especially suited for automotive camera applications. It is function and pin compatible with the MAX9271. In high-bandwidth mode, the parallel-clock maximum is 116MHz for 12-bit linear or combined HDR data types.

The embedded control channel operates at 9.6kbps to 1Mbps in UART, I2C, and mixed UART/I2C modes, allowing programming of serializer, deserializer, and camera registers independent of video timing.

For driving longer cables, the IC has programmable pre/deemphasis. Programmable spread spectrum is available on the serial output. The serial output meets ISO 10605 and IEC 61000-4-2 ESD standards. The core supply range is 1.7V to 1.9V, and the I/O supply range is 1.7V to 3.6V.

The MAX96705A is available in a 32-pin (5mm x 5mm) TQFN package with 0.5mm lead pitch, and operates over the -40°C to +115°C temperature range.

Description

The MAX96705A coax evaluation kit (EV kit) provides a proven design to evaluate the MAX96705A high-bandwidth gigabit multimedia serial link (GMSL) serializer with spread spectrum and full-duplex control channel, through the use of a standard FAKRA coax or STP cable. The EV kit also includes Windows Vista®- and Windows 7-compatible software that provides a simple graphical user interface (GUI) for exercising features of the device.

For complete GMSL evaluation using a standard FAKRA coax cable, order the MAX96705A EV kit and a companion deserializer board (the MAX96706 or MAX96708 EV kit are referenced in this document). For testing with STP cable, also order the MAXCOAX2STPHSD adapter kit and refer to its data sheet. Only one adapter kit is required per link (connecting the serializer and deserializer boards).

Note: In the following sections, MAX96705, MAX96705A, and the term “serializer” refer to the MAX96705A ICs and MAX96706/08 and the term “deserializer” refer to the MAX96706 or MAX96708 ICs.

Note: This document applies to both coax and STP EV kits. This document covers coax cables, but the information provided applies equally to STP cables.
